Recombinant DNA techniques are also a cornerstone of the biotechnology industry. One example is the generation of genetically engineered plants to produce an insect toxin called Bt toxin.
Ethernet switches and hubs can be connected to a router with multiple PC ports to expand a LAN. Depending on the capabilities (kinds of available ports) of the router and the switches or hubs, the connection between the router and switches/hubs may require either straight-thru or crossover (null-modem) cables.
An ethernet network is a situation in which multiple computers are connected to one another and share the same Internet protocol address. An ethernet network has multiple computers on the same server. The benefit in this is that multiple networks do not need to be created.
